Asn1CharRange Class Reference

Inheritance diagram for Asn1CharRange:

Asn1CharSet List of all members.

Detailed Description

This class is used to represent a permitted alphabet that is specified
as a large, continuous range of characters. An example of this can be found in the following extract from T.124:
simpleTextFirstCharacter UniversalString ::= {0, 0, 0, 0}
simpleTextLastCharacter UniversalString ::= {0, 0, 0, 255}
SimpleTextString ::= BMPString (SIZE (0..255))
(FROM (simpleTextFirstCharacter..simpleTextLastCharacter))
This class is mainly for internal use by the compiler when generating
methods that encode/Decode PER charater string components containing permitted alphabet constraints.
